ResinTech coconut shell granular activated carbon (GAC) is used in combination with KDF media to significantly extend the life of filter cartridges. KDF 55 media is a redox media that removes chlorine, and reduces heavy metals. KDF 85 removes hydrogen sulfide and reduces iron by the redox process and filtration. Both KDF redox media are bacteriostatic and inhibit the growth of microorganisms in the filter.

About Carbon / KDF

Activated carbon has remarkable cleaning and absorptive properties, which makes it an effective way to purify water. Chemicals and contaminants in the water are bonded at a molecular level to the carbon, effectively removing them from the water.

The addition of stabilized or reticulated KDF 55 / KDF 85 media is used to complement activated carbon filters. It aids in the removal of chlorine when treating municipal waters, and extends the carbon’s life, while limiting bacterial growth in the filter. Additionally, the KDF has the ability to remove water-soluble cations via the oxidation-reduction process, resulting in a cost effective alternative to chemical treatment.
